摘要 针对磁悬浮控制力矩陀螺径向磁悬浮转子强非线性、强陀螺效应耦合对系统稳定性的影响,建立了磁悬浮转子多通道非线性动力学模型与功放模型,分析了磁悬浮转子系统的强陀螺效应耦合性,提出了一种考虑功放环节的α逆系统结合滑模控制器的解耦控制方法,并对其进行了仿真试验。结果表明,该方法对磁悬浮转子系统有良好的解耦效果与鲁棒性。 Aiming at the influence of strong non -linearity,strong gyroscopic effect coupling of radial magnetically sus-pended rotor on system stability of magnetically suspended control moment gyroscope,the multichannel non -linearity dynamical model and power amplifier model are built for magnetically suspended rotor.The strong gyroscopic effect coupling of magnetically suspended rotor system is analyzed.The decoupling control method is presented,which com-bines αinverse system with power amplifier link and sliding mode controller,and the simulation test is carried out.The results show that the method has good decoupling effect and robustness for magnetically suspended rotor system.
